[Dovecot] my.cnf reading support in MySQL backend
by Luca Longinotti 01 Jan '08

01 Jan '08

I hope this ml is the right place to send this... Anyway, I'd very much like for the MySQL backend to call mysql_options, so that it'll read the settings defined in MySQL's my.cnf under the [client] section. This allows to set a whole slew of MySQL specific settings for the MySQL connection, for example to enable the compressed protocol, set charsets, enable SSL client verification, and much more. A patch is attached that implements this. See http://dev.mysql.com/doc/refman/5.0/en/mysql-options.html for more info. -- Best regards, Luca Longinotti aka CHTEKK LongiTEKK Networks Admin: chtekk(a)longitekk.com Gentoo Dev: chtekk(a)gentoo.org SysCP Dev: chtekk(a)syscp.org TILUG Supporter: chtekk(a)tilug.ch

[Dovecot] deliver: keep existing From_ line
by Alexander 'Leo' Bergolth 01 Jan '08

01 Jan '08

Hi! I'm using procmail to filter my email. (I have to use it because of various features that are not supported by sieve.) However, I'd like to deliver mail to my mboxes using dovecots deliver program in order to update index files and speed up mbox access. Using "| $DELIVER -m <mboxname>" in my procmail receipes, everything works fine, except that the envelope sender address is mangled. deliver sets it to MAILER-DAEMON, even though it is already provided in the first line of the mail. I cannot use the "-f <address>" options of deliver, since procmail doesn't provide the envelope-sender address in a variable. (I'd have to extract it from the first line of the mail using a separate receipe, which isn't very efficient.) Is there a way to keep the already existing "From " line? Thanks in advance, --leo -- e-mail ::: Alexander.Bergolth (at) wu-wien.ac.at fax ::: +43-1-31336-906050 location ::: Computer Center | Vienna University of Economics | Austria

[Dovecot] Building path to maildir
by Michel Bulgado 01 Jan '08

01 Jan '08

Hello everyone Happy new year . This is the first time I address to the list I have the following situation and I need help from all you people I have dovecot 0.9-11 and i want to migrate to a superior version like dovecot 1.0 looking forward to implement quotas in my system , and use the function deliver with postfix. My Scenario is as follow Dovecot + LDAP (ADS) + postfix My actual version is : 0.99.11 This is my actual configuration: Protocols = imap pop3 imap_listen = * pop3_listen = * login_dir = /var/run/dovecot-login login = imap login = pop3 default_mail_env = maildir:/var/spool/virtualmail/%d/%n mbox_locks = fcntl auth = dovecot-auth auth_mechanisms = plain auth_default_realm = CASA.CULT.CU auth_userdb = ldap /etc/dovecot-ldap.conf auth_passdb = pam dovecot auth_user = root auth_verbose = yes auth_debug = yes dovecot-ldap.conf hosts = ldap.casa.cult.cu base = ou=CASA,dc=casa,dc=cult,dc=cu dn = cn=unix-conector,cn=Users,dc=casa,dc=cult,dc=cu dnpass = ***** ldap_version = 3 deref = never scope = subtree user_global_uid = 500 user_global_gid = 500 user_attrs = mail,/var/spool/virtualmail/%d/%n,,,, user_filter = (&(objectClass=user)(!(objectClass=computer))(sAMAccountName=%n)) I see many changes in this new version. One of them is : -Renamed default_mail_env to mail_location - many changes in ldap queries With the new version my problem is when to dovecot tries to detect or builds the way where it´s stored the mailbox of my users. In /var/spool/virtualmail/%d/%u , it does not detect the domain when asking to my active directory (w2k) and consequently takes a value of my default realm = casa.cult.cu in this case the default domain where authenticate my users. My configuration in the new version of dovecot: protocols = imap pop3 protocol imap { listen = * } protocol pop3 { listen = * } login_dir = /var/run/dovecot/login login_chroot = yes login_greeting = Dovecot ready. mail_location = maildir:/var/spool/virtualmail/%d/%u mail_debug = yes mbox_read_locks = fcntl mbox_write_locks = fcntl protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota } protocol lda { postmaster_address = postmaster(a)example.com mail_plugins = quota auth_socket_path = /var/run/dovecot/auth-master } auth_executable = /usr/libexec/dovecot/dovecot-auth auth_verbose = yes auth_debug = yes auth default { mechanisms = plain passdb pam { args = dovecot } userdb ldap { args = /etc/dovecot-ldap.conf } userdb prefetch { } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = virtualmail group = virtualmail } } } dict { } plugin { quota = maildir:storage=10240 } user_attrs = mail,/var/spool/virtualmail/%d/%n,,,, The attribute mail in the old version returns to me user(a)casa.com or user(a)casa.cult.cu this way dovecot can build the way with no problems at all. But in this late version something is happening, it only takes the value %n= user , but not %d = domain . It´s not working. do you have any idea how I can solve this I beg your pardon for my poor English. ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

[Dovecot] Maildir
by Peter Fraser 01 Jan '08

01 Jan '08

I have been trying to set up dovecot with postfix to use at work. I'm trying to configure dovecot to authenticate against active directory and postfix the same. I installed dovecot 1.0.10 on FreeBSD 7.0 beta 2 When I telnet in the get authentication ok but an error suggesting that there is no Mailbox belonging to that user. I am using Maildirs. How can I now create a Maildir with the proper permissions for that virtual user? Thanks for any assistance.

[Dovecot] Enhanced Kerberos support
by Richard A Nelson 31 Dec '07

31 Dec '07

The recent addition of auth_gssapi_hostname is a welcome addition, but a little more is needed for multi-homed (or multi-domained) sites. SSH recently added this enhancement to address this common need: GSSAPIStrictAcceptorCheck Determines whether to be strict about the identity of the GSSAPI acceptor a client authenticates against. If “yes” then the client must authenticate against the host service on the current hostname. If “no” then the client may authenticate against any service key stored in the machine’s default store. This facility is provided to assist with operation on multi homed machines. The default is “yes”. Note that this option applies only to protocol version 2 GSSAPI connections, and setting it to “no” may only work with recent Kerberos GSSAPI libraries. I've heard that other daemons support multi-names by instead of using gethostname(), obtain the hostname of the interface that the request came in on. Can either approach be looked at for dovecot ?

[Dovecot] Help with logging in and getting mail
by Andrew Falanga 31 Dec '07

31 Dec '07

Hi, Very new to dovecot and to using POP3/IMAP (from this perspective anyway). First things first, per the instructions from the web site: dovecot version: 1.0.5 dovecot config: # 1.0.5: /usr/local/etc/dovecot.conf protocols: imap pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login verbose_proctitle: yes first_valid_gid: 0 mail_extra_groups: mail mail_location: mbox:~/mail/:INBOX=/var/mail/%u mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain digest-md5 user: vmail passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf Please help me diagnose what is causing the following problem. Essentially, this user is a virtual user. I have it so that the system user, vmail, is the basket into which all virtual users e-mail goes. If my understanding is correct (and please enlighten me if it's not), mail aliases are setup to "map" aliased names into a real account. From there, dovecot will return e-mail to the virtual user based upon the "To" field of the e-mail, correct? I have some aliases in my sendmail config that do just this. From the error below, it would seem that dovecot is actually authenticating the virutual user "jdunkin" in this case, but can't get some directories made. I've seen on my FreeBSD system that each system user has a "mail" file in the directory, /var/mail/<userid>. What needs to be done further? Also, how do I ensure that virtual users are able to get their mail as well as system users?

After reading of the problems encountered on other systems, the 1.1 beta 13 version (main part as well as Deliver) seems to inexplicably be running just fine under OS X 10.5.1 for some reason. :^) Jerry

[Dovecot] Time just moved backwards
by Neal Becker 31 Dec '07

31 Dec '07

This wins the 2007 award for strangest (or most amusing) log message: dovecot: Time just moved backwards by 13 seconds. This might cause a lot of problems, so I'll just kill myself now. It does, unfortunately, leave dovecot dead, which was pretty mysterious to me. Maybe it could re-exec instead?
